    HIFalpha targeted for VHL-mediated destruction by proline hydroxylation: implications for O2 sensing (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-04-09
    Description: HIF (hypoxia-inducible factor) is a transcription factor that plays a pivotal role in cellular adaptation to changes in oxygen availability. In the presence of oxygen, HIF is targeted for destruction by an E3 ubiquitin ligase containing the von Hippel-Lindau tumor suppressor protein (pVHL). We found that human pVHL binds to a short HIF-derived peptide when a conserved proline residue at the core of this peptide is hydroxylated. Because proline hydroxylation requires molecular oxygen and Fe(2+), this protein modification may play a key role in mammalian oxygen sensing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ivan, M -- Kondo, K -- Yang, H -- Kim, W -- Valiando, J -- Ohh, M -- Salic, A -- Asara, J M -- Lane, W S -- Kaelin , W G Jr -- New York, N.Y. -- Science. 2001 Apr 20;292(5516):464-8.

    Human hypertension caused by mutations in WNK kinases (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-08-11
    Description: Hypertension is a major public health problem of largely unknown cause. Here, we identify two genes causing pseudohypoaldosteronism type II, a Mendelian trait featuring hypertension, increased renal salt reabsorption, and impaired K+ and H+ excretion. Both genes encode members of the WNK family of serine-threonine kinases. Disease-causing mutations in WNK1 are large intronic deletions that increase WNK1 expression. The mutations in WNK4 are missense, which cluster in a short, highly conserved segment of the encoded protein. Both proteins localize to the distal nephron, a kidney segment involved in salt, K+, and pH homeostasis. WNK1 is cytoplasmic, whereas WNK4 localizes to tight junctions. The WNK kinases and their associated signaling pathway(s) may offer new targets for the development of antihypertensive drugs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilson, F H -- Disse-Nicodeme, S -- Choate, K A -- Ishikawa, K -- Nelson-Williams, C -- Desitter, I -- Gunel, M -- Milford, D V -- Lipkin, G W -- Achard, J M -- Feely, M P -- Dussol, B -- Berland, Y -- Unwin, R J -- Mayan, H -- Simon, D B -- Farfel, Z -- Jeunemaitre, X -- Lifton, R P -- New York, N.Y. -- Science. 2001 Aug 10;293(5532):1107-12.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Howard Hughes Medical Institute; Yale University School of Medicine, Boyer Center for Molecular Medicine, 295 Congress Avenue, New Haven, CT 06510 USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11498583" target="_blank"〉PubMed〈/a〉
